PIE rrnrivnvrrnd Ann CRIMPING MACHINE.

Application filed July 23, 1913. Serial No. 780,718.

To all whom it mag concern:

citizen of the United States, residing at Rochester, Monroe county, NewYork, have invented a new and useful Pie Trimming and Crimping Machine,of which the following is a specification.

My invention has for its object to improve the construction of pietrimming and crimping machinery by affording a construction that isadapted to be successfully operated with pics of different sizes, by amechanism" that is of comparatively simple construction and can bereadily operated.

A further purpose of the invention resides in the provision of. astructure which enables a pie to be trimmed and crimped bytwooperations, the arrangementfbeing such that it is possible to eliminateadhering or sticking of the dough to the crimping devices, as they areseparated, leaving the pie ina finished state.

Still another purpose of the invention is,

to afford a crimping mechanism embodying a plurality of sectionsarranged in a manner to permit them to come incontact suc-' cessivelywith different portions of the pie successive order. I

To these and other ends the invention con sists in certain improvementsand combina tions of parts all as will be hereinafter more fullydescribed, the novel features. being pointed out in the claims at theend of the.

specification. l p. In the drawings Flgure 1 lsa view In side elevationof a preferred embodiment of my invention, the trimmer being brokenaway;

Fig. 2 is a bottom plan View; Fig. 3 is a top plan view; and Fig. A is aside elevation partly in section.

Similar reference characters throughout the several figures indicate thesame parts.

In the embodiment shown, there is pro vided a frame embodying a base mand a pair of vertical guides 7?. upon which the trimming and crimpingdevices are movable. Arranged for movement on the guides n is a carriage6, provided with a handle'j by which it may be operated, and controlledby a spring k which acts to hold the carriage normally in raisedposition. Secured to the carriage i is a support or casting g whichcarries the trimming and crimping devices, and to this end isconstructed with a plurality of arms extending downwardly andSpecification of Letters Patent.

Be it known that I, GEORGE G. GRIM, a

portions in attached to the trimmer a at the lower edge of the latter.The trimmer a is preferably in the formof a truncated cone being.constructed of, spun aluminum or a flexible grade of tin, and isinclined slightlyaway from the upperiportionsof the arms on the casting9, so as t'opermitits upperpart to have a more orless free andyieldingaction I as it contacts with theple tin. J The trimmer maybeattached to the arms of the casting by rivet ng or in any other suitablemanner.

By reason of the conical shape 'of-theftrimmer, it is possible toutilize the same machine in connectionwith pics of different sizes, andoperation, the trimmer is moved downwardly by depressing the carriage 5,until its inner surface comes contact with the dough against the edgeofthe pie tin,v

severing the dough by a downward shearmg action as shown in Fig. 1. p

After the trimming operation has taken place, it is desirable to crimpthe dough around the edge of the tin in a manner which Wlll prevent thedough from adhering to the crlmpmg devices as the latter are moved away,and to this end I employ a crimper consisting of a serles of independentcrimpingmembers which are actuated by separate springs. Thls ispreferably accomplished by the structure shown, comprising a series ofcrimping members 6, each of which is connec'tedby a rod d to a head 0,the rod (Z bemg guided in openlngs mythe casting g and provided withrocker-arms e pivoted in suitablebearings in the head 0. Springs fconnect the casting g with the crimping members Z), and serve tohold'the latter nor mally in elevated position. After the trimmingaction has takenplace, when it is de sired to crimp the edge of the pie,the head 0 is depressed, moving the. crimpers against the action of thesprings f, until they engage the pie. It will be observed that by reasonof the independent mounting of the several crlmplng members, they maycome into operatlve engagement wlth the pie at successive intervals andbe raised in a similar order, the head a partaking of a rolling motionto effect this result, and by this means it will be seen that onesection of the crimper may be moved from the dough while the othersections are still in engagement,

and this gradual separation prevents the dough from being pulled awayfrom the pie. The inclination of the rods d permits the crimping membersto move downwardly Patented Oct. 13, 1914.

and at the same time outwardly until they engage the upper surface ofthe pie, the arrangement being such as to permit successful cooperationbetween the crimper and trimmer for any sizes of pics for which themachine may be constructed.

- The pies are supported upon aholder 1 Which is mounted upon a standardcarrying at its opposite end another holder 1 the standard beingreversible to accommodate tivo'difier'ent sizes of pies. The casting gis removably supported on the carriage 2', and held in. place by a setscrew and thumb nut 7L. l i

While I have described the invention in a particular embodiment, it isto be understood that I am not limited to the precise construction setforth, and I intend to cover by this application any modifications, thatmay embody a conical trimmer or a sectional crimper employed separately.or in combination.

Copies of this patent may be obtained for a crimper'movable relativelyto the trimmer,

said crimper comprising a plurality of independently movable sections.

2. In a machine for trimming and crimptrimmer having an interior surfaceadapted to engage pies of different sizes, of a series of crimpingmembers movable within the trimmer, said crimping members beingindependently and yieldably supported.

3. In a machine for trimming and crimping pics, the combination with aguide, of support vertically movable on the guide, a conical trimmerattached at its lower edge to the support, the upper edge of the trimmerbeing free, and a crimper movable rclatively to the trimmer and mountedupon the support.

4. In a machine for trimming and crimping pies, the combination with aguide, of a support vertically movable on the guide, a conical trimmerattached at its lower edge to the support, the upper edge of the trimmerbeing free, and a series of crimping members independently mounted uponthe support and movable relatively to the trimmer.
